Worry

Yan Jin Nian.

A very famous phsycologist and also a member of Human Association. A young woman who had made a lot of contribution and caused a lot of people to feel terrified when facing her. Because they knew very well that they couldn't say any lies in front of her if they didn't want to be persecuted. 

Her ability to detect lies from the truth was so strong that people were scared when they saw her. Because they felt that she was able to see through them, dug out their deepest secret and stripped them bare.

This feeling was very uncomfortable.

But Yan Jin Nian was not a person who liked to meddle in other people's business. As long as they were not involved in any crimes, she would not pursue them. 

Still, this ability of hers made many people very uncomfortable.
